Germany: Holcim Deutschland has signed a memorandum of understanding with Cool Planet Technologies (CPT) to build a pilot CO2 capture unit at Holcim’s Höver cement works, near Hannover, based on Hereon’s PolyActive membrane technology. The objective of the unit is to demonstrate the performance, economics and operability of the capture technology at scale. Following this the partners will seek to establish a framework for the technology’s implementation in Holcim’s other cement plants in Germany.
Initial tests are scheduled to commence in the first quarter of 2022 with the first phase of the project, capturing 5600t/yr of CO2, scheduled for start-up in the second quarter of 2023. If successful, it is planned to expand the unit in two further phases capturing 170,000t/yr and 1.3Mt/yr starting-up in 2024 and 2026 respectively. The final phase will capture over 90% of the carbon dioxide emissions from the Höver plant and deliver the CO2 in high-purity liquid form for use or sequestration.
CPT is working with Hereon, part of the Helmholtz Association of Research Centres, Germany’s largest research organisation, to commercialise their PolyActive membrane technology after a decade of development. This technology is designed to capture CO2 from carbon rich gas streams and has already been technically proven in the laboratory and piloted in two coal-fired power stations.
